    observation more or less frequently for sixteen years. I shall here only bring before you the evidence of the effect of pressure in causing the altered chemistry of the urine. The first specimen of the urine I saw was made at 9.30 a.ra., one hour and a-half after breakfast, the patient remaining in bed. It was clear, acid to test paper, not light coloured ; sp. gr. 1022*5. It did not coagulate when boiled nor when nitric acid was added; but the acid made the colour deeper. On the surface there was a slight appearance of oil; one or two blood-globules were also seen. The second specimen was passed at 11.30 a.m., two hours after he had got up. It was of a yellowish-milk colour, quite thick, and spontaneously coagu- lated, so that it could not be poured from the bottle. The sj)ecific gravity was lOlT'O. It was very feebly acid to test paper. Nitric acid and heat gave a considerable precipitate. Under the microscope I saw blood-globules in some quantity. No trace of oil-globules, but a large quantity of very minute molecular matter, scarcely resolvable by a magnifying power of 320 times. No trace of casts of the. ducts could anywhere be found. Little films of coagulum could be seen, containing many blood-globules. Treated with ether, the ethereal solu- tion was clear; tlie urine below was cloudy, but on long standing became clear. The ethereal solution on evaporation gave a great mass of oil-globules, but with the microscope no decidedly crystalline fat was seen. In the' Philosophical Transactions,' Part II. (1850), you may see some further experiments on the influence of rest arid motion on this patient in lessening or increasing the albumen in the urine previous to or after food was taken :— Last food was taken at 5.15 p.m. yesterday. He lay in bed this morning till 9.30 a.m. 10 p.m. last night.—Urine milky. ■6.40 a.m.—Urine yellow, slightly milky, acid, contained a little albumen. 8.10 a.m.—Urine clear, healthy-looking, made just before breakfast, which consisted of boiled milk (a pint), with sago and bread with a little butter; the specific gravity of the urine was 1021'3 ; it gave no coagulum with heat and acid.
